SeedSigner - DIY Bitcoin Hardware Wallet

SeedSigner is an open-source, DIY Bitcoin hardware wallet that puts you in complete control of your private keys. Built on affordable, widely-available components, it eliminates dependency on proprietary devices while maintaining enterprise-grade security. It is stateless by design (it never stores private keys) and functions as a “Swiss Army Knife” of offline Bitcoin tools: key generation, transaction signing, multisig coordination, seed backup, and address verification. Software setup: Follow our SeedSigner setup guide to choose the correct software, flash the microSD card and start your device. The guide also covers blank-screen troubleshooting.
